Class 445
ELECTRIC LAMP OR SPACE DISCHARGE COMPONENT OR DEVICE
MANUFACTURING
Class Definition:
This is the residual and generic class of process and
apparatus for the manufacturing, fabrication, repair,
salvage, assembly, disassembly or other treatment of an
electric lamp, liquid crystal display device or an electric
space discharge device which process or apparatus is not
elsewhere classified.
(1) Note. An electric lamp is defined for the purpose of
classification as a device for converting electric energy
into visible light or ultraviolet light.
(2) Note. An electric space discharge device is defined for
the purpose of classification as including any device which
is intended to have an electric current flow between two
spaced parts or electrodes, at least part of the path
followed by the discharge constituting a gas, vapor, or
vacuum. Examples of an electric space discharge device
include spark gap, spark plug, radio tube, X-ray tube,
cathode-ray tube, laser tube, arc tube, gas or vapor
discharge lamp, flash lamp and lightning arrester of the
electric space discharge type.
LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
The line between this class and all other classes which
provide for either apparatus or process for the manufacture
or treatment of electric lamp, liquid crystal display device
or electric space discharge device is that all combined
process and all apparatus which are intended to perform a
plurality of different processes are classified in this class
when one of the operations performed is an operation
specifically provided for in this class. For the lines
between particular classes not included in the general line
above, see the notes to this section, below, and References
to Other Classes, below.
For electric lamp and electric space discharge device,
including the structure of a self-baking or Soederberg
electrode which is formed from a plastic mass during the
operation of the device, see References to Other Classes,
below.
The line between this class (445) and Class 29 is as follows:
(a) where a claim is presented which recites manufacturing
another structure, e.g., a lamp base, PCB; either specific or
nominal and specific Class 445 device manufacture, placement
of the original will be in Class 445; (b) where there is
specific recited manufacture of another structure and, as a
step in that manufacture, a nominally recited Class 445
device is nominally united to the base, placement is in Class
29 (merely screwing a light bulb into a base is considered
nominal); and (c) the manufacture of other structures
intended to be used with a Class 445 device is in Class 29 or
other manufacturing classes.
The subject matter of the class (445) was found in Class 316
and abolished subclasses 25.1+ of Class 29. No other
portions of Class 29 have been screened for Class 445 subject
matter.
